How to fix a Casio DR-220TA Calculator that does not work at all?
If your Casio Calculator isn't working at all, it could be due to a defective power transformer. Check the secondary voltage of the transformer. Alternatively, a defective LSI could be the culprit, in which case you should check the waveforms of each pin.
What to do if my Casio Calculator has poor printing or missing digits?
If your Casio Calculator is experiencing poor printing, the motor isn't stopping, or digits are missing, the timing signal might be bad. Check the detector of the printer block and the timing signal. Another potential cause is a defective printer magnet.
What to do if my Casio DR-220TA has no display?
If your Casio Calculator displays nothing, the issue could stem from several causes. First, check for voltage at VF1 and VF2. Second, inspect the pulse signals from the LSI to ensure there's a digit or segment signal. Finally, if VF1, VF2, digit, and segment signals are all okay, the display tube itself may be defective.
Why is my Casio DR-220TA display poor?
If your Casio Calculator is producing a poor display, it could be due to a defective LSI. Alternatively, there might be short or open circuits between the digit and segment signals between the LSI and display tube. A defective display tube could also be the cause.
